Bitcoin was made as a new electronic cash and new kind of money. Bitcoin can be used as payment system, to do some transactions, and to save and earn money. The real life usage of this bitcoin is to advance our technology when it comes to our payment system or transactions. You don't have to go in any central banks you just have to open your connection and online. Bitcoin was really made to lessen our hassle and worries and to make our life easier. It alsl give chances and opportunities to earn a lot to avail and sustain our daily needs.
But the function of bitcoin as a payment system has not been effective at this time. Well, we know that its use as a payment system is still limited with regard to legality. So I think the function of bitcoin is real and effective today is as a commodity and investment.
